EmbeddedWall: Ispezione Pacchetti CAN-FD/Ethernet in Tempo Reale, SecOC e Filtraggio PQC

EmbeddedWall fornisce firewall hardware on-chip, unità di protezione della memoria (MPU) e filtri di interconnessione bus che isolano fisicamente acceleratori crittografici post-quantistici, memorie di chiavi segrete e pool di seed da periferiche DMA non attendibili.

Architectural Layers & Protocols

On-Chip Interconnect Plane (ARM CoreLink NIC-400 / AXI4 Multi-Layer Fabric): Interconnecting CPU cores, high-speed DMA masters, memory controllers, and crypto accelerators.
Hardware Transaction Filtering (Hardware Access Control Lists (ACLs)): Inspecting master IDs, privilege levels, and address ranges on every bus read/write cycle.
DMA Attack Isolation Barrier (System Memory Management Unit (SMMU / IOMMU)): Preventing compromised PCIe, USB, or Ethernet DMA controllers from probing crypto memory buffers.
Security Violation & Fault Controller (Hardware Bus Abort & State Scrubbing Logic): Terminating illicit bus cycles with zero-delay SLVERR responses and asserting security alerts.

Key Metrics: 1 Cycle (Firewall Inspection Latency) | 100% (DMA Isolation Coverage) | Hardware (Enforced Privilege Separation) | Zero-Leak (SRAM Scramble Protection)
